Keynote: The Social Bases of Healing

  • Abstract
Humans are eusocial animals who have evolved to thrive in social groups. Human, as well as other eusocial species (e. g. ants and bees), heal through social means.  Every human society has had designated healers and particular healing practices.  Many issues people can find problematic, including some related to fluency, will benefit from treatments specific to the issue, but such treatments are universally more effective when delivered in the context of social healing.  Social healing in humans involves the relationship between healer and patient as well as the expectations created in that relationship.   Firstly, evidence from psychotherapy, placebo studies, and medicine is presented, showing that people feeling distress benefit from social healing, regardless of whether their problems are medical or psychosocial. This includes distress that may be experienced related to fluency disorders and/or the way in which differences in fluency are perceived by society. Next, the mechanisms of social healing are presented, which include combatting loneliness, affective coregulation, and transmission of expectancies.  Finally, means to improve the quality of care through social means is discussed.
  • Learning Outcomes
  1. To understand how humans have evolved to heal through social means
  2. To be knowledgeable of the research that supports the therapeutic relationship as an evidence-based component of interventions.
  3. To understand how social healing can be used to improve quality of care.






We are delighted to announce a keynote panel, discussing the conceptualization of cluttering. The panel will be led by Dr. Florence Myers (Adelphi University, Garden City, New York), who has devoted the past thirty years toward an understanding of cluttering and its relation to stuttering. 

Dr. Myers helped to co-organize the first world congress on cluttering held in Katarino, Bulgaria in 2007, at which time the International Cluttering Association was ‘born’.  Dr. Myers is a Fellow of the American Speech-Language-Hearing Association and recipient of the Deso Weiss Award for contributions to the field of cluttering, conferred by the Stuttering Foundation and the International Cluttering Association. Her works have been translated into French, Polish, and Bulgarian.  

The panel’s keynote presentation at One World, Many Voices: Science and Community introduces the Three-Pronged Approach to the Conceptualization of Cluttering (TPA-CC). Dr. Myers had an integral role in development of the TPA-CC and we are privileged to have her join us in Japan to explain the development of this key piece of work. This presentation will be of interest to delegates who clutter, stutter, or stuttering/clutter, and to those with a background in clinical or research work.  The panel will offer perspectives on a definition of cluttering, explore similarities and differences between cluttering and stuttering, and discuss ways in which cluttering can be conceptualized. Also featuring on the panel will be Dr. Charley Adams and Dr. Susanne Cook.

Saturday 14th July 2018 Keynote presentation: Dr. Florence Myers, Dr. Charley Adams, Dr. Susanne Cook

Keynote: The Three-Pronged Approach to the Conceptualization of Cluttering (TPA-CC).

  • Abstract

This keynote address will provide perspectives on cluttering. A recent survey with Speech-Language Pathologists (SLPs) in the United States (Cook & Adams, 2016) revealed the need for more education and training on cluttering. In response to this survey, the International Cluttering Association formed an ad-hoc committee tasked with the development of a comprehensive conceptualization of cluttering. Several extant perspectives will be reviewed, to be followed by a detailed discussion of the nature of cluttering using the ICA-endorsed TPA-CC (Three-Pronged Approach to the Conceptualization of Cluttering).   Much research is still needed to arrive at a universally accepted definition of cluttering. Until such time, we can complement research-based findings through equally rich clinical experience and observations toward a conceptualization of the nature of cluttering, and how it may differ from stuttering.

  • Learning Outcomes
  1. To identify the speech-language dimensions contributing to cluttering

  2. To describe the ‘three prongs’ of the TPA-CC

  3. To differentiate aspects of cluttering and stuttering using the TPA-CC



Koichi Mori pic 2.2We can now confirm that our next keynote speaker for One World, Many Voices: Science and Community will be Dr. Koichi Mori, M.D., Ph. D.

Dr. Mori graduated from the University of Tokyo Medical School in 1981 and earned his Ph.D. in Neuroscience from the University of Tokyo Graduate School in 1988. Dr. Mori has been involved with research into stuttering since 1992 using neuroimaging techniques as well as behavioral and therapeutic efficacy studies. Currently Director of the Department of Medical Treatment and Head of the College of the National Rehabilitation Center for Persons with Disabilities in Tokorozawa, Japan, Dr. Mori is a founder member of the Japanese Society for Stuttering and other Fluency Disorders (JSSFD).

Dr. Mori’s current work includes clinical work with adults who stutter using cognitive behavioral therapy (CBT). Current research includes a comprehensive large-scale prevalence study of preschool children who stutter in Japan and development of a group CBT approach for adolescents and adults who stutter.

Dr. Mori’s keynote speech will focus on the use of cognitive behavioral therapy with adults who stutter in a group therapy setting. This interesting keynote will offer an insight into therapy options for people who stutter in Japan, and will increase awareness of the use of CBT with people who stutter both in Japan and internationally. We anticipate this will lead to interesting debate between delegates of all nationalities regarding the availability of different approaches to living with stuttering across the globe and inspire new ways of thinking about, working and living with stuttering in people’s own lives.

Keynote: The use of Cognitive Behavior Therapy (CBT) in a group setting with adults who stutter.

  • Abstract

Treatment of adult stuttering typically requires many and frequent sessions (e.g. 30 weekly sessions), which may not be practical for some people who stutter (PWS), nor for clinicians in Japan due to their scarcity. Although the primary reason for using cognitive behavior therapy (CBT) in our adult stuttering treatment is to improve the success rate and QOL, it can also help reduce frequent clinic visits. Our group therapy program comprises five 3-hour sessions over five weeks. Stuttering is postulated as interference to the innate ability to speak freely and fluently, with subconscious conditioning, maladaptive coping behaviors (MACBs) and a complex vicious cycle of cognition, emotion and behavior. MACBs are painful and triggered by the intent "not to stutter", and contribute to stuttering symptoms. CBT is implemented as follows to address these issues comprehensively: (a) Most importantly, the therapy goal should not be fluency improvement, but better and easy communication, because aiming at it consciously would rather hinder natural fluency, though fluency is a frequent byproduct of the CBT therapy. (b) Similarly, attention control should be directed away from stuttering, through voluntary stuttering, prosody modulation exercises, and mindfulness meditation. (c) The mechanisms of anxiety and anticipation in stuttering are explained for better coping. (d) Natural utterances are induced with various methods including speech shadowing, which can also help people with cluttering-stuttering. (e) Challenges to speak without checking for difficult words are encouraged. After the group approach, reduction was observed in OASES impact scores and fluency efforts as well as dysfluency frequencies.

  • Learning Outcomes

1. The attendee will learn about certain possible underlying processes and maintaining mechanisms of stuttering, with reference to the Levelt's speech process model and subconscious conditioning learning.

2. The attendee will be able to explain the specific training exercises in the context of cognitive behavior therapy (CBT).

3. The attendee will be able to recognize the pros and cons of the group format for stuttering treatment.




We are thrilled that our final keynote announcement is Annie Bradberry and Dr Mitchell Trichon, who will be speaking together on the topic of"Nurturing Partnerships and Cooperation in Our Stuttering/Cluttering World". Annie and Mitch will be speaking about the fascinating topic of ways to build and nurture partnerships and cooperation within the stuttering /cluttering community.

Keynote: Nurturing Partnerships and Cooperation in Our Stuttering/Cluttering World    

  • Abstract

This session will provide a deeper understanding of the importance of collaboration between all involved in the stuttering and cluttering communities; from the people whose speech is affected, to the researchers that explore the many facets of stuttering/cluttering, to the clinicians who help their clients find their voice.  We will touch upon aspects of the communities' evolution and reveal some of the strengths and barriers which have fostered and tapered our successes.  Additionally, we will identify and seek to promote alliances between individuals, between professionals, between organizations and amongst all the above.  We hope to emulate the spirit of the Congress by appreciating our different perspectives and recognizing we are in a prime position to work synergistically to improve the lives of people who stutter/clutter while preserving the values and customs of all groups involved. 

  • Learning Outcomes
  1. Participants will describe various organizations, programs and projects that serve people who stutter/clutter.
  2. Participants will discuss current barriers between people who stutter/clutter, clinicians, and researchers and how to overcome them.
  3. Participants will identify ways in which collaborative efforts have helped to better the lives of people who stutter/clutter.
